Two examples of physical changes are form and shape. These are physical changes because they are visible to the naked eye.

Colour and temperature are two examples of chemical change as the colour and temperature change chemically during an experiment. ]]> 2022-09-12 02:57:55 UTC https://padlet.com/tperera/6wbontqdptwq1w7t/wish/2291631929 Practise Question 1 https://padlet.com/tperera/6wbontqdptwq1w7t/wish/2291641857 Chemists would not write a chemical equation for melting chocolate because chocolate is not a chemical element ]]> 2022-09-12 03:10:16 UTC https://padlet.com/tperera/6wbontqdptwq1w7t/wish/2291641857
